I designed by box to be able to use a lipo as well as a 12v power supply. The only downside is I can only switch between the two if I can connect it to a computer with Escribe. I'd like to be able to use my vapestation at my desktop, get in the car and use it off the cigarette lighter than switch it to battery mode when I've reached my destination. The problem is the only way I can do this is if I bring a laptop which is a pita. So I'm requesting a firmware update to allow this switching using the onboard buttons. I really hope this would be possible!
